The 3299P-1-105LF is a 3/8" square multiturn cermet trimming potentiometer designed for industrial sealed applications requiring precision resistance adjustment. This device features a 1 megohm resistance value (code 105) with ±10% standard tolerance, 25 turns of effective travel, and infinite resolution for smooth voltage and resistance adjustability of ±0.01% and ±0.05% respectively. The potentiometer operates across a temperature range of -55°C to +125°C with a power rating of 0.5 watts at 70°C, and includes solderable pins with 100% tin-plated (RoHS-compliant) termination. Its sealed construction, U.L. 94V-0 flammability rating, and robust mechanical design with 3.0 oz-in maximum torque make it suitable for precision instrumentation, signal conditioning circuits, and industrial control systems where reliable fine-tuning and environmental resistance are essential.
